Wordpress execute javascript file only if user is not logged in

I'm trying to execute a javascript file in wordpress only if the user is not logged in, but I can't see why it's not working. This is the code I'm using:
<?php
if ( is_user_logged_in() ) {
echo 'Ok!';
} else {
wp_enqueue_script(
'ads'
);
}
?>
And this is what I have in functions.php to register the file:
wp_register_script(
'ads',
get_bloginfo('template_directory') . '/js/ads.js'
);
Any ideas? Thanks in advance!

wp_enqueue_script() should be run on the wp_enqueue_scripts hook. This should also be encapsulated in a function, or at least a closure/anonymous function.
Side note, you'll want to start properly formatting/indenting code now - future you thanks you!
A. You're checking if a user "is" logged in. You can just make sure that is_user_logged_in() is returning false with the use of the "Not" Logical Operator: !.
B. You don't need to register your script, as wp_enqueue_script will register it for you. You really only need to register scripts if you're getting more fancy like loading scripts only if a shortcode is active on a page.
C. Typically you'll want to prefix your script/style handles, since they should be unique, there can be conflicts otherwise.
D. Typically you'll want to use get_template_directory_uri() or get_stylesheet_directory_uri() over get_bloginfo() since get_bloginfo( $directory_type ) is literally just a wrapper for those functions.
Something like this will get you started:
add_action( 'wp_enqueue_scripts', 'load_ads_script' );
function load_ads_script(){
if( !is_user_logged_in() ){
// The "!" makes sure the user is _not_ logged in.
wp_enqueue_script( 'jacob-k-ads', get_stylesheet_directory_uri().'/js/ads.js' );
}
}

TypeError Jquery(...).function is not a function

I'm having an issue with calling a method that has got me completely stumped. I have a set of methods in an external js class that's used for libraries outside core js for the WP theme.
(Sorry About the unending line)
external.js
(function(a){
var b=0;a.fn.mobileMenu=function(c){function e(a){return a.is("ul, ol")}function f(){return a(window).width()<d.switchWidth}function g(c){if(c.attr("id")){return a("#mobileMenu_"+c.attr("id")).length>0}else{b++;c.attr("id","mm"+b);return a("#mobileMenu_mm"+b).length>0}}function h(a){if(a.val()!==null){document.location.href=a.val()}}function j(b){b.css("display","none");a("#mobileMenu_"+b.attr("id")).show()}function k(b){b.css("display","");a("#mobileMenu_"+b.attr("id")).hide()}function l(b){if(e(b)){var c='<div class="td_mobile_menu_wrap"><select id="mobileMenu_'+b.attr("id")+'" class="mobileMenu">';c+='<option value="">'+d.topOptionText+"</option>";b.find("li").each(function(){var b="";var e=a(this).parents("ul, ol").length;for(i=1;i<e;i++){b+=d.indentString}var f=a(this).find("a:first-child").attr("href");var g=b+a(this).clone().children("ul, ol").remove().end().text();c+='<option value="'+f+'">'+g+"</option>"});c+="</select></div>";b.parent().append(c);a("#mobileMenu_"+b.attr("id")).change(function(){h(a(this))});j(b)}else{alert("mobileMenu will only work with UL or OL elements!")}}function m(a){if(f()&&!g(a)){l(a)}else if(f()&&g(a)){j(a)}else if(!f()&&g(a)){k(a)}}var d={switchWidth:td_switch_width_normal,topOptionText:"Menu",indentString:"-"};return this.each(function(){if(c){a.extend(d,c)}var b=a(this);a(window).resize(function(){m(b)});m(b)})}})(jQuery);
And then the core
site.js
jQuery('#td-top-menu .sf-menu').mobileMenu();
and i end up with the error:
Uncaught TypeError: jQuery(...).mobileMenu is not a function
Somewhere along the line, i've managed to break this code and yet i'm not truly sure. I've stripped my header down to just the necessary scripts and nothing causes the error. My current JQuery CDN is the standard downloaded one from google cdn. I was under the impressional that i would get this issue because it cannot resolve the method. But if both scripts are there (I've logged external.js method to see that the script isn't broken), i don't see why it's throwing this error.
The site is http://whatzbuzzing.com to see the error first hand. As a wordpress distribution, i was under the impression that something has gone wrong outside the two files shown because they haven't been edited at all.

In accordance with the order of requests in Chrome Networks panel, you're loading external.js before jquery.min.js. Maybe you could try to fetch jquery.min.js before fetching of external.js? Sorry if I missed anything in your question.

this happens when multiple jquery files are loaded, not a very uncommon thing in a wordpress site.
in your case the problem is here
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.12.0.min.js"></script>
jquery comes bundled with wordpress, all you have to do is to properly enqueue your script with jquery as a dependency
function enqueue_my_external_script() {
wp_enqueue_script( 'externaljs', '//example.com/path/to/external.js', array( 'jquery') );
}
add_action( 'wp_enqueue_scripts', 'enqueue_my_external_script' );
if you're calling this from a theme you can use get_template_directory_uri to get the theme directory's url like this
function enqueue_my_external_script() {
wp_enqueue_script( 'externaljs', get_template_directory_uri() . '/path/to/external.js', array( 'jquery') );
}
add_action( 'wp_enqueue_scripts', 'enqueue_my_external_script' );
wp_enqueue_script function
wp_enqueue_scripts action hook

Link Javascript and JQuery Wordpress

I know this problem is pretty common at this moment and many people are asking the same question but for know I can't find any good solutions.
I wonder how i should implantate my scripts to wordpress?
This how far I have come:
function my_scripts_method() {
wp_register_script("contact-form", get_bloginfo("stylesheet_directory") . "/form/contact-form.js");
wp_enqueue_script("contact-form");
wp_register_script("form", get_bloginfo("stylesheet_directory") . "/form/form.js");
wp_enqueue_script("form");
wp_register_script("validate", get_bloginfo("stylesheet_directory") . "/form/validate.js");
wp_enqueue_script("validate");
wp_register_script("answercheck", get_bloginfo("stylesheet_directory") . "/contact/answercheck.js");
wp_enqueue_script("answercheck");
}

You've created a function my_scripts_method() and did you call it anywhere? Hooked it to something?
Try with
add_action( 'wp_enqueue_scripts', 'my_scripts_method()');
Also you can enqueue your scripts directly. So your
wp_register_script("contact-form", get_bloginfo("stylesheet_directory") . "/form/contact-form.js");
wp_enqueue_script("contact-form");
Will be
wp_enqueue_script("contact-form", get_bloginfo("stylesheet_directory") . "/form/contact-form.js");
If you have no dependencies. Also I'd use get_stylesheet_directory_uri() instead of your get_bloginfo("stylesheet_directory").
get_stylesheet_directory_uri()
EDIT
Try putting in your functions.php
add_action( 'wp_enqueue_scripts', 'my_scripts_method');
function my_scripts_method() {
wp_enqueue_script('contact-form', get_template_directory_uri().'/form/contact-form.js','','', true);
wp_enqueue_script('form', get_template_directory_uri().'/form/form.js','','', true);
wp_enqueue_script('validate', get_template_directory_uri().'/form/validate.js','','', true);
wp_enqueue_script('answercheck', get_template_directory_uri().'/contact/answercheck.js','','', true);
}
Alternatively you can put get_stylesheet_directory_uri() instead of get_template_directory_uri(), if it doesn't work. But it should (unless you don't have anything in the /form and /contact folders).

Wordpress ACF Include input.js not working

I'm using acf v4 plugin for wordpress.
I'm trying to include the input.js. This is the code that i added
function input_admin_enqueue_scripts()
{
// Note: This function can be removed if not used
// register ACF scripts
wp_register_script( 'acf-input-progressbar', $this->settings['dir'] . 'js/input.js', array('acf-input'), $this->settings['version'] );
wp_register_style( 'acf-input-progressbar', $this->settings['dir'] . 'css/input.css', array('acf-input'), $this->settings['version'] );
// scripts
wp_enqueue_script(array(
'acf-input-progressbar',
));
// styles
wp_enqueue_style(array(
'acf-input-progressbar',
));
}
But the javascript is never called. I added the console.log function to test the call :
(function($){
console.log("Test input.hs");
....
This is the name that i used for my plugin : acf-progressbar
Files :
acf-progressbar-v4.php
acf-progressbar.php

You have to hook in your function with something like the following:
add_action( 'admin_enqueue_scripts', 'input_admin_enqueue_scripts' );
The above call will enqueue the script on the admin side of WordPress which is what I assume you want due to the function name. If you want to enqueue them everywhere then use this instead:
add_action( 'wp_enqueue_scripts', 'input_admin_enqueue_scripts' );
The calls to add_action need to take place in the global space. So in the end you'll have something like:
function input_admin_enqueue_scripts() {
// Note: This function can be removed if not used
// register ACF scripts
wp_register_script( 'acf-input-progressbar', $this->settings['dir'] . 'js/input.js', array('acf-input'), $this->settings['version'] );
wp_register_style( 'acf-input-progressbar', $this->settings['dir'] . 'css/input.css', array('acf-input'), $this->settings['version'] );
// scripts
wp_enqueue_script(array(
'acf-input-progressbar',
));
// styles
wp_enqueue_style(array(
'acf-input-progressbar',
));
}
add_action( 'admin_enqueue_scripts', 'input_admin_enqueue_scripts' );
If you already have your function hooked in with a call to add_action then the problem is probably that you have your style and script named the same:
wp_register_script( 'acf-input-progressbar' ...
wp_register_style( 'acf-input-progressbar', ...
I would switch these to the following and see if that works:
wp_register_script( 'acf-input-progressbar-js' ...
wp_register_style( 'acf-input-progressbar-css', ...

wp_localize_script with handle jquery - wordpress script

I'm looking for next solution. I want faster website so I concat all JS to one file and placed in footer. One of my js is jQuery and I use next hook and function:
if (!function_exists("ef_theme_scripts")) {
function ef_theme_scripts() {
wp_deregister_script('jquery');
wp_register_script('jquery', get_template_directory_uri() . '/js/min/script.min.js', null, null, true);
wp_enqueue_script('jquery');
$params = array(
'ajax_url' => admin_url('admin-ajax.php'),
'ajax_nonce' => wp_create_nonce('user_nonce'),
);
wp_localize_script( 'jquery', 'ajax_object', $params );
}
}
add_action('wp_enqueue_scripts', 'ef_theme_scripts');
I called my handle "jquery" because there can be some scripts (e.g. from plugins) which wants use jquery so I need add called this handle "jquery".
Everything works great except localize. When I rename script handle for example to "custom-jquery" then wp_localize_script works without problem.
I use WP 4.0.1. Thanks for help

IMPORTANT! wp_localize_script() MUST be called after the script it's being attached to has been registered using wp_register_script() or wp_enqueue_script().
More info

I asked a similar question and got the working solution here :
wp_localize_script not working with jquery handle
Basically this has to do with the way that WP works with the jQuery handle, you'll need to
deregister jquery
deregister jquery-core
Use the jquery-core handle on your script
at the end register jquery, with a dependency on jquery-core and passing false for the $scr attribute
Code:
wp_register_script( 'jquery', false, array( 'jquery-core' ), false, true );
